A rotor wing aircraft with a propulsion apparatus is disclosed. The aircraft has a rotating mast configured to rotate the rotor wing and the propulsion apparatus includes a pole mechanically connectable to the rotating mast of the aircraft. An electric turbine is placed at one of the ends of the pole, powered by a battery, and configured to rotate the pole around an axis of the rotating mast in such a way that the rotation of the pole can be used to rotate the rotor wing. The pole is made of carbon fiber.

Aircraft propulsion and torque mitigation technologies for aircraft are described. In embodiments, the disclosed technologies enable the provision of rotational torque for rotating the rotor blades of a vertical lift aircraft, while mitigating or even eliminating the need for counter torque methods and apparatuses such as tail rotors and counter rotating blades.

Various mechanisms for adjusting pitches of propeller blades are described. For example, the pitch adjustment mechanism may include a propeller hub enclosing a geared mechanism that cooperates with a compound gearbox having first and second planetary stages to adjust pitches of propeller blades. Alternatively, the pitch adjustment mechanism may include a propeller hub enclosing a pitch adjustment assembly that utilizes tension cables and torsion springs, or rack-and-pinion structures, to adjust pitches of propeller blades. Using any of the various mechanisms, the pitches of propeller blades may be rotated at least 90 degrees, and up to and exceeding 360 degrees, in order to effect thrust reversals and/or adjust thrust profiles.
